Interlock® Aluminum Roofing — all-climates performance specs for Grand Boulevard, Illinois
| Spec / Rating | Climate / Risk Factor + What It Solves |
|---|---|
| Wind resistance: 120+ mph (193+ kph) | Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events. |
| Fire rating: Class A (with proper assembly) | Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating. |
| Hail resistance: UL 2218 Class 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.) |
| Corrosion resistance: aluminum (won’t rust) | Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments. |
| Heat / UV durability: baked-on coating system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance. |
| Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam) | All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather. |
| Expected lifespan: 50+ years | Long-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments. |
| Warranty: Lifetime-Limited, non-prorated + 50-year transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |

What our customers are saying:
I was happy with them . They called me and gave me all the info They arrived on time and he loves business.
They exceeded my expectations by delivering the product as described, and installing it professionally, and in a timely manner. no conflicts or issues.
John was really excellent and knew his stuff! If we had the extra money, we would have done it. He was A+++
If you want the best quality shingles that are secured on all 4 sides, contact Interlock. You could let me know when you would pick up the yard sign, or if I should toss it after a couple of weeks. I'm still waiting to hear from my insurance (State Farm) if I get a discount for having a much higher quality roof on the house.
Absolutely. I'd tell anyone to get an aluminum roof. [Surveyor note: Mr. Levin didn't seem to understand the survey process, but was willing to provide feedback. So I only asked for the likely to recommend rating and the open-ended questions to make it easier for him.]
I felt they were very professional. I would consider them going forward on a different home.
I think Interlock Roofing could have improved on the last walkthrough. They did a last walkthrough at dusk, and it was too dark to see everything that could be picked up. A lot of little pieces of nails and screws were found the following morning. Overall, I was very satisfied with what they did, though. We had a lot of people who stopped and looked. A couple of people asked us about the roof. We told them to call the number if they were interested.
John is a nice young man. The appointment seemed to "drag on" too long. We told him styles we did NOT like and he still wanted to tell us about them-- a bit of a waste of time.
The timing was a little bit of a concern because it took at least a week or so and that was surprising, but other than that, it was pretty good
Don't say you do sky lights, you obviously do not have skill or accessibility to materials in this area, took almost two years to complete the sky light installation. Got the run around to where window was and when it would be installed. The sky light you installed is not the quality we expected after a nearly two year delay. We had no idea it would just be set in with 2"x4" pieces of wood and would not be finished on the inside, leaving us to waterproof and tile on the inside of the shower. Old one was flush with no exposed raw wood. Big disappointment! Jesse and Sal did the best they could with what was given on the outside of the roof.
